A 20-year-old Los Angeles man is behind bars after Riverside County sheriff's deputies say he forced his way into a Temescal Valley home, brandished a firearm, and robbed the people inside. David Cordero was arrested and booked into jail on suspicion of home invasion robbery, assault with a deadly weapon, and brandishing a weapon following the confrontation on Glen Eden Road.
Lake Mathews Sheriff's Station deputies were called to a home on the 25000 block of Glen Eden Road on August 8, according to KTLA. Callers reported that the suspect had brandished a firearm and demanded valuables before fleeing the scene. The Riverside County Sheriff's Office later identified Cordero as the suspect and said deputies searched the surrounding area, deploying K9 and aviation units before locating and taking him into custody.
Cordero, who is from Los Angeles, was arrested on suspicion of targeting the Temescal Valley home and robbing the victims inside. He was booked into the Robert Presley Detention Center in downtown Riverside, a seven-story facility that opened in 1989 and holds roughly 1,100 to 1,500 inmates, according to the Riverside County Sheriff's Office. The sheriff's office said it has released no further details on whether Cordero and the victims knew each other, leaving that question unresolved for now.
A Rural Community Without Its Own Police Force
Temescal Valley is an unincorporated, census-designated community along the Interstate 15 corridor that recorded a population of 26,232 in the 2020 U.S. Census, according to Wikipedia. Because the area has no municipal police department, residents depend entirely on Riverside County Sheriff's deputies for emergency response. That responsibility falls to the Lake Mathews Sheriff's Station at 9 Latitude Way in Corona, which was established in March 2023 as the department's 12th patrol station specifically to cover 158 square miles of unincorporated western Riverside County, per Patch.
It is not the first violent incident the station's deputies have handled in the area. Hoodline previously reported on an armed homeowner in nearby Lake Mathews who fatally shot a break-in suspect who forced entry into a residence on Hidden Peak Lane in May 2025, which triggered a homicide investigation. Lake Mathews station deputies have also responded to a violent assault in Temescal Valley and a barricaded domestic violence standoff in the same community in recent years.
Potential Charges Carry Steep Penalties
Cordero's booking on suspicion of home invasion robbery exposes him to significant prison time under California law. First-degree robbery committed inside an inhabited dwelling carries a state prison sentence of 3, 4, or 6 years and is classified as a violent felony strike under the state's Three Strikes law, according to Cron Israels and Stark. Under Penal Code Section 211, robbery is defined as taking property from someone's immediate presence against their will through force or fear, and it cannot be reduced to a misdemeanor.
If prosecutors can establish that Cordero personally used a firearm during the robbery, California's so-called 10-20-Life law under Penal Code Section 12022.53 mandates an additional consecutive 10-year prison term, according to Eisner Gorin LLP. Separately, the assault with a deadly weapon charge he was booked on is a wobbler offense that can be charged as a felony carrying up to four years in state prison, or as a misdemeanor carrying up to a year in county jail, per the Shouse Law Group.
Investigation Continues
Deputies have not disclosed what specific valuables were taken or whether Cordero acted alone. Anyone with information is asked to call Deputy Becerril at the Lake Mathews Sheriff's Station at 951-272-5600.
